no clue how split screen works. with that said, does it look the same on both screens? does it look the same for both screens if both cameras are in the same place? from what i can see in the screenshot, it looks a bit like the sprite orientation is being calculated for the wrong screen.
Seems like you need to force each camera to compute the ribbon separately then. I feel like this should be a non-issue though and have no idea on how to go about this.
It seems like something that should just work. If you don’t find anything with a cursory search I suggested submitting a bug report. At the very least you’re more likely to get attention from a dev.
